cHARn s QGLASS, F HARTLEY, TEXAS V 011:. PUMP I Application filed July30,

This inventionrelates to an oil pump and container especially designedfor use in transferring oils such as lubricating oils, from a drum ortank, to the crank casing of an automobile v The primary object of theinvention is to provide a device of this character which will transferoil from a container to the crank casing of an automobile, eliminatingany possibility of foreign matter such as dust, rain or snow, enteringthe oil.

- Another object of the nvention is to provide a device of thisoharacterwhich will facilitate the filling of crank casings by forcing the oilfrom the body portion of the device as distinguished from the usualmethod of allowing the oil to move by gravity into the crank casing.

A still further object of the invention is the provision of means forregulating the quantity of oil passing from the body portion of thedevice, so that the amount of oil may be accurately dispensed.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawings:

Figure 1 is an elevational view of an oil pump constructed in accordancewith the in vention and showing the same as positioned for filling.

Figure 2 is a longitudinal sectional view through the pump.

Figure 8 is a sectional view taken'on line 33 of Figure 2.

Figure 4: is a sectional view taken on line 44 of Figure 2.

Figure 5 is an enlarged longitudinal sectional view through the pipethat is positioned in the drum or tank containing the oil. 7

pump comprises a cylindrical body portion 5 formed of translucentmaterial, so that the operator may view the oil contained in the bodyportion of cylinder 5. Heads 6 and 7 respectively are positioned overthe ends of the body portion 5 and fit against the gaskets 8 to providea fluid tight connection between the ends of the body portion andtheheads,

there being provided rods 9 extended the heads into close engagement-with the gaskets.

through openings in the heads for drawingiifio The reference character10 designates-a hollow handle portion provided with a hand grip 11 atits outer end, the handle portion 10 being designed to receive the rackbar 12to which the plunger13 is secured. Cooperating with the rack bar12 is a pinion 14: mounted on the shaft 15 that extends through the head6, there being provided a crank handle 16 mounted on one endof the shaft15, so that the shaft maybe rotated to move the pinion .over the rackbar 12 and cause the rack 'barto move longitudinally of the handleportion 10, resulting in a relative 1 movement of the plunger 13 toidrawliquid into the body portion 5 to fill the body portion, and force theliquid from the body portion into the crank casing to be filled. v 1

At one end of the rack bar 12 is a depending lug 17 which lug is adaptedto be engagedby the sliding bolts 18 that are spring pressed and movethrough'openin gs in the handle 10. Bell crank levers 19 connect withthe sliding bolts 18, and have connection" with grip 11, so that-theoperator may bymoving the levers 21, withdraw the pins 18 to allow therack bar 12 and plunger to move freely.= It will also be seen that dueto this construction, certain of the pins may be extended in the path oftravel of the lugto restrict movement of the rack 12, so that only apredetermined quantity of oil willbe dispensed- 'The' referencecharacter 22 designates a discharge pipe to which the curved pipe 23 isconnected, the curved pipe 23-having 'connection with the valve casing24, in which the valv'e'25 moves, the va1ve 25 b in oper- 7 normalclosed position. a

In order to facilitate the use of thedevice, a pipe such as indicated at31 is positioned 1n the drum or barrel containing the 011 supply, thepipe being supplied with a fvalve to the tank upon reverse movementchamber 32 at its upper end, in Whichthe one-way valve 33 is positioned,the valve 33 acting to permit oil to be drawn through the pipe 31, butprevent the oil from returning of the plunger in thebody portion 5.

Securedto the upper end of the valve housing 32 is a union 3 1 having acurved upper surface 35 to receive the curved lower surface 36 of thevalve casing 24. A vent pipe indicated at 37 has connection with thedrum or supply tank, whichin the present showing is indicated by thereference letter A, the vent pipe being supplied with a cap- 38 formedwithopenings to register with openings of the vent pipe, so that the cap38 may be rotated to bring the openings thereof into alignment with theopenings of the o pipe, when it is desired to remove oil from the drumor tank. The cap may be moved.

a to close the openings to prevent foreign matter from entering thetankA when oil is not being drawn from the drum or tank A.

A drain valve 39 is in communication with I claim: a In a device of theclass described, a body portion, a hollow handle secured to the bodyportion, a rack bar operating through the handle and extending into thebody portion, a depending lug at one end of the rack bar, sliding boltsextending into the hollow handle and disposedin the path of travel ofthe lug, for restricting movement of the rack bar, bell crank leversconnected with the sliding bolts, bars connected with the bell cranklevers, and levers connected with the last mentioned bars and disposedadjacent to the hande for operating the bars and sliding bolts to movecertain of the bolts to allow the rack bar to move throughthe handle, aplunger on one end of the rack bar, and means for moving the rack barthrough the bodypor tion. 1 I 1 In testimony that I claim the foregoingas my own, I have hereto'aifixed my signature.

the body portion and provides means where-. l i

by the contents of the body portion may be drained, should it be desiredto clean the l body portion.

In the operationof the device, the valve caslng 24 is positioned on theunion 34, in a manner as shown by Figure 1 of the drawings. Theilevers21 are now operated to Withdraw pins 18 from the handle 10, whereuponthe handle 16 is operated to move the plunger 13 longitudinally of thebody portion 5, and towards the handle 10,drawing liquid from thedrum Ainto the body portion'5.

, It is ofcourse understood thatip'rior to the operation of the plungeras described,

the operator opens the valve 25 by exerting a pressureon the extension29. After the body portlon 5 has been filled, the valve agaln opened andthe pins 18 are withdrawn,

whereupon the handle 16 is rotated in theopposite direction to forcethe'liquid from the I 7 body portion 5 and into the clan I casingof amotor vehicle to be filled. I,

Should it be desired to dispense one quart 'of 011, the lever 21connected with the first pin, or pin nearest to the gripll, is operatedto move the. pin out of the path oftravel of the-lug on the rack bar-l2.v As the hande 16 is rotated to-forc'e the oil from thebody por-
